    What clocks are stable to use? I did +40 on both base clock and memory clock and my 3dmark11 score went up 300 points. What are you using?

    Using a modified bios (each bios has a set voltage) and also to expand the clock range.

    I'm currently maxing out on stock voltage, so thats 135 in the core and 480 on the mem, temps never go beyond 77.

    Meaker, are those clocks damaging for the card when active 24/7?
